Is it possible to map "mostRecentComment" to a field?

[Nicolas Bier]

The variable "mostRecentComment" seems to have been designed for email notification, however we would like to be able to display the most recent comment in a multi-line text field. Is it possible?

[Alejo Villarrubia [Adaptavist]]

This could be the code of a scripted field:

import com.atlassian.jira.component.ComponentAccessor

def commentManager = ComponentAccessor.getCommentManager()
def comments = commentManager.getComments(issue)
comments ? comments.last().body : null
